Proof without words for surface area of a sphere
I like your proof. The proof for area under a cycloid also required some simple geometrical calculations which I am willing to still consider as a "proof without words". It is still intriguing though that it is not easy to find a natural proof mapping the area of a circle with twice the radius of the sphere to the surface area of the sphere. |

Locating a submatrix within a matrix
Thanks Tsuyoshi. Do we know anything of the problem if B is relatively sparse? |
